STEAM oonnnivsna application filed August a; 1925. "seria1`na4ae7a- This invention relates to steam condensers' of the surface type, the object being to pro` vide an improved easing construction for such I condensers. which shall be cheaper, lighter and stronger than those heretofore used.

In accordance with this invention, the condenser casing is built up of steel beams or shapes of suitable form, according to the form l oiC condenser shell desired, and upon thesev beams is supported a light shell to enclose the condensing space, this shell being supported by the beams at such intervals and in such mannerA as to enable comparatively thin rolled sheet metal or other suitable material to be used. l am thus enabled to make a very light, strong and cheap condenser casing, and

to avoid the internal cross bracing and interference with tube arrangement usual in large condensers.

For a full understanding of the invention, there is shown in the accompanying drawings orms of condenser casings embodying the invention in preferred forms, and these constructions will now be described in detail and the features forming the invention then be specilically pointed out in the claims.

ln the drawings- Figure l is a diagrammatic cross-section of a condenser shell of the common cylindrical torni embodying the invention;

Figure 2 is a central longitudinal section of the same;

Figure 3 is a view similar to Fig. l, showing a modification with the beams on the outer side ot the casing;

Figure l is aside view of Figure 3, and

Figures 5 and Glare views similar to Fig. l, showing the invention applied to condensers ot' other forms.

Referring now especially to Figs. 1 and 2, A is the exhaust inlet and B the condenser shell, which preferably is of rolled sheet metal but may be of cast metal or any other suitable material, supported by a series'of beams C, shown as ot' standard T-orm in cross-section and as extending entirely about the inner side of the condenser B across the exhaust inlet A, a very strong form oi construction being secured by these circular or ring beams. These beams are suilicient in number and-so spaced that l.a comparatively light shell may be used. t islf'oundin practice* that `these beams. do notsubstantiallyinterfere with the free passageof the exhaust from the exhaust 'inlet A to theY condensing surfaces', even! though placed at the closest intervals necessary in practice.` The condensing tubes 10 are shown inv dotted lines as arranged in shallow beltsfand in convolutionsvfor steam distribution, and the'usualjhot-Well ll at the bottom of' thel condenser is shown', the' central beam C passing acrossthetop of this hot-Well.

lln Figs; '3 and a` construction similar to Fig. is shown, except that the beams D are applied on t-he outer sidefoi'theshell B, pref! erably x'tendin'g upward on 4the exhaust connection A, asshown, and the shellis'also supported at'the exhaust connection by beams E extending across. the exhaust opening.

In Fig. 5 an octagonal shaped condenser" shell F is shown, and the beams are in the form of bracing Jframes G of triangular form, each extending over two sides of the Octagon so as to form a rectangular condensing space between them.

In Fig. 6 a condenser casing of the bowl or half cylinder form is shown, with beams I of any suitable cross-section extending over the outer side of the casing H, Vthe exhaust opening extending the entire 'width of the casing and having supporting beams crossing the exhaust opening or not, as desired.

It will be understood that the invention is not to be limited to the form or arrangement of parts illustrated, as construct-ions f embodying the invention will be varied widely according to the form of condenser desired, while retaining the invention defined by the claims.

What is claimed is:

l. A steam condenser having a shell` formed of plate material and supported by metal shapes arranged outside the condensing space of the'condenser and spaced to supl port the shell against the condenser stresses?V withoutv internal cross-bracing in `the condensing space.

2. A Vsteam surface condenser having a shell formed of plate material and supported by metal shapes outside the condensing space.y

. Assrenoa trol. 'woaTHinero-N rUMP nunV of the condenser and crossing the exhaust opening and spaced to support the shell against the condenser stresses without internal cross-bracing in the condensing space.

3. A steam surface condenser of circular form having a shell formed of plate material and supported by circular beams extending around the condensing space and across the exhaust opening and spaced to support the shell against the condenser stresses Without internal cross-bracing in the condensing space.

4. In a steam condenser, a shell having an exhaust opening and formed of plate material and supported by metal shapes conforming y to the shape of the shell and crossing the eX- haust opening, saidmetal shapes spaced to support the shell against condenser stresses Without internal cross-bracing in the condenser.

5. In a steam condenser, a shell having an exhaust opening and formed of plate material, metal shapes Within said shell and conforming to the shape of thel shell and crossing the exhaust opening and lying Whol- 1y Without the'condenser space in the condenser, said metal shapes spaced to support the shell against condenser stresses Without internal cross-bracing in the condenser.

In testimony whereof, I have hereunto set my hand.

CHARLES E. LUCKE.
